Input Torque Calculator:

Enter the values of Output Torque, T_o(N.m) and Gear Ratio, GR to determine the value of Input Torque, T_i(N.m).

Input Torque Formula:

The input torque formula is utilized to determine the torque required at the input of a mechanical system, such as a gearbox, to achieve a desired torque at the output, taking into account the gear ratio.

Input Torque, T_i(N.m) in Newton metres, is calculated by dividing the Output Torque, T_o(N.m) also in Newton metres, by the Gear Ratio, GR which is a dimensionless number.

Input Torque, T_i(N.m) = T_o(N.m) / GR.

T_i(N.m) = input torque in Newton metre, N.m.

T_o(N.m) = output torque in Newton metres, N.m.

GR = gear ratio.

Input Torque Calculation:

1. Suppose you need an output torque of 600 N.m to drive a mechanical system and you have a gearbox with a gear ratio of 3:1. Calculate the input torque required.

Given: T_o(N.m) = 600N.m, GR = 3

Input Torque, T_i(N.m) = T_o(N.m) / GR.

T_i(N.m) = 600 / 3

T_i(N.m) = 200N.m.

2. For a heavy-duty application, an input torque of 300 N.m is applied and the available gearbox has a gear ratio of 4:1. Find the output torque needed to meet this requirement.

Given: T_i(N.m) = 300N.m, GR = 4

Input Torque, T_i(N.m) = T_o(N.m) / GR.

T_o(N.m) = T_i(N.m) * GR

T_o(N.m) = 300 * 4

T_o(N.m) = 1200N.m.
